That link has the cast and credits for the 1958 film but also lists it as color, so there is inconsistancy in the listing itself.Seems hard to imagine it's the Rosalba Neri / Mel Welles flick at this point.

In regards to the full length version, ZDD put together a ratty comp that mixes the footage from the German TV print, some from the Swedish VHS and a few bits from the New World Corman edit that came out on Embasy. They 16 x 9 the full screen inserts which squashes them and the image is bad on these brief sections, but it does seem to cobble together the 'director's cut '.Corman kept all the nudity and gore intact but pruned reems of expository footage ( and character motivation ) and it the process made Welles vision seems choppy and semi incoherent.The uncut version is a far better film, hands down.
